MuukTest
You know that you could be testing more to catch bugs earlier, but QA testing can take a lot of time, effort and resources to do it right. MuukTest can get growing engineering teams up to 95% coverage of end-to-end tests in just 3 months. Our QA experts create, manage, maintain, and update E2E tests on the MuukTest Platform for your web, API, and mobile apps at record speed. We begin exploratory and negative tests after achieving 100% regression coverage within 8 weeks to uncover bugs and increase coverage. The time you spend on development is reduced by managing your testing frameworks, scripts, libraries and maintenance. We also proactively identify flaky tests and false test results to ensure the accuracy of your tests. Early and frequent testing allows you to detect errors in the early stages your development lifecycle. This reduces the burden of technical debt later on.

Google Compute Engine
Compute Engine (IaaS), a platform from Google that allows organizations to create and manage cloud-based virtual machines, is an infrastructure as a services (IaaS). Computing infrastructure in predefined sizes or custom machine shapes to accelerate cloud transformation. General purpose machines (E2, N1,N2,N2D) offer a good compromise between price and performance. Compute optimized machines (C2) offer high-end performance vCPUs for compute-intensive workloads. Memory optimized (M2) systems offer the highest amount of memory and are ideal for in-memory database applications. Accelerator optimized machines (A2) are based on A100 GPUs, and are designed for high-demanding applications. Integrate Compute services with other Google Cloud Services, such as AI/ML or data analytics. Reservations can help you ensure that your applications will have the capacity needed as they scale. You can save money by running Compute using the sustained-use discount, and you can even save more when you use the committed-use discount.

Description

IBM® Rational® Test Virtualization Server software facilitates timely and regular testing throughout the development process. By virtualizing portions or the entirety of an application or database, it eliminates dependencies, allowing software testing teams to initiate their work without waiting for those resources to become available. This approach helps decrease the expenses associated with setting up and managing complex application environments. Furthermore, it promotes agility and predictability through continuous integration testing implemented earlier in the development cycle. Seamless integration with IBM Collaborative Lifecycle Management enhances collaborative testing efforts. The virtualization features include data-driven and correlated response sequences, as well as comprehensive stateful database emulation. A centralized repository for virtualized environments allows for the reuse, deployment, and alteration of configurations to explore various testing scenarios. In addition, IBM Rational Test Virtualization Server encompasses all functionalities found in IBM Rational Performance Test Server, supporting the validation of application performance effectively. With these capabilities, organizations can ensure that their applications are rigorously tested and optimized before deployment.
